help me out here

i was talking to my uncle yesterday who is an electrical engineer for ford

and we were talkin about my truck (99 f350 with 12'' lift) and he said i should put on some headers cause ill get better mileage. what do you think about this? what would be the best brand or kind like shorty or long to get? and how much to have them installed?

And while im at it could you lead toward the best way to go for exhaust on a v10?

thanks,
josh

Headers won't help mileage.

You get bad fuel mileage because you have a 12 inch lift and probably have larger tires with that 12 inch lift.

Lifting a truck 12 inches increases the drag coefficient severely, which lowers your fuel mileage. Larger tires also have more rolling resistance.

I recommend either the OBX SS shorty headers below at $299.00 plus $25.00 shipping or the Doug Thorely long-tube headers, if still available.

Headers won't help mileage. It doesn't take much power to cruise on the road and your stock manifolds are just fine for that.

Personally, I wouldn't sink money in a small engine in a large truck. It's still going to be slow any way you cut it. More aggressive gears will help more than anything so that the engine doesn't have to work too hard.

Banks TorqueTubes after you re gear and possibly lower that truck.

Headers might have gained me .3-.5 mpg. Maybe. But I think it's more of a result of not having an exhaust leak.

Overall - you won't increase mileage with headers.
